INTRODUCTION

The Shure Model WH30 is a light yet rugged headset microphone. Designed
for vocalists and instrument-playing vocalists, the WH30 utilizes a high quality
electret-condenser cartridge suitable for all applications where mobility,
comfort, low microphone-visibility, and high sound quality are required.
Because of its cardioid (unidirectional) pickup pattern, the WH30 provides
isolation from extraneous sound sources and high gain-before-feedback.

The wireframe and gooseneck adjust to any head size and shape. An
integrated elastic CROAKIES



headband comfortably pads and secures the
headset. The WH30 is supplied with two snap-on windscreens, clothing clip,
storage bag and cable-management device.

FEATURES

• Smooth, natural frequency response comparable to professional condenser

hand-held microphones

• Lightweight wireframe and headband adjust for a secure, comfortable fit

• Extra-strong, small-diameter microphone cable resists breakage

• Moisture-proof cartridge housing

• Sturdy gooseneck-boom holds mic securely in place

• lsolation shock mount for reduced handling noise

• Matte black finish for low visibility

• High input clipping level helps avoid overload distortion

• Low self-noise and high sound pressure level capability

• Reliable at temperature and humidity extremes

MODEL VARIATIONS

• WH30TQG: For wireless use, the WH30TQG has a 1.5m (5 ft.) high-flex cable

and a mini TA4F connector for direct connection to Shure body pack transmit­ters. (Note: for information about use with Shure W10BT or other transmitters
without a mini TA4F connector, contact Shure Customer Service).

• WH30XLR: For wired applications, the WH30XLR is supplied with a 1.5m (5

ft.) hi-flex cable and high quality mic preamplifier (RPM420) with a three pin
XLR connector. The RPM420 preamplifier requires phantom power from any
11 – 52 V source.

COLLAPSIBLE MICROPHONE BOOM

The WH30 headset features a collapsible boom for shipment and storage.
Before wearing the headset, unfold the boom by rotating it away from the
wireframe until it snaps into place. Refold for storage or transportation.

WEARING THE HEADSET

Place the headset wireframe around your head so that the elastic headband
band lay horizontally across the back of your head and the ends of the
wireframe fit over your ears. You may position the elastic headband either
above or below the wireframe for the greatest comfort and stability. The blue
“SHURE” logo should face outward (see Figure 2).

ADJUSTING THE HEADSET

• If the headset feels loose or uncomfortable, carefully bend the sides of the
wireframe to make it tighter or looser (see Figure 4A). The angle of the wire­frame earpieces may also need adjustment (see Figure 4B).

• Adjust the tension of the elastic headband across the back of the head by slid­ing it up or down the ends of the wireframe (see Figure 5).

USING THE CABLE RETAINER AND CLOTHING CLIP

Use the cable retainer on the wire frame of the headset to position the
microphone cable as desired. The supplied spring-loaded clothing clip secures
the microphone cable to the user’s clothing to help avoid entanglement.

POSITIONING THE MICROPHONE

For maximum gain-before-feedback, position the microphone and boom so
that the microphone is within 13 mm (1/2 inch) of the right corner of your mouth
(see Figure 3). This will also help minimize breath noise or “popping”.

CONNECTING THE WH30 TO A SOUND SYSTEM

WIRELESS APPLICATIONS (WH30TQG)

1. Connect the mini TA4F connector from the WH30 to a wireless microphone

transmitter such as the Shure T1 bodypack transmitter.

2. See the user guide for your wireless transmitter and receiver system for ad-

justing gain and other parameters.

WIRED APPLICATIONS (WH30XLR)

Connect the output of the RPM420 preamplifier to an input channel of a
mixing or recording console. Most consoles will provide phantom power to the
RMP420 preamplifier. If phantom power is unavailable, use a separate
phantom power supply such as the Shure PS1A.

WASHING THE ELASTIC HEADBAND

When necessary, remove and wash the elastic headband according to these
steps.

1. Remove the microphone cable retainer from the wireframe.

2. Slide the elastic headband off the wireframe.

4

ELASTIC HEADBAND ADJUSTMENT

3. Wash the headband in mild, soapy water and rinse it in clean water.

4. Allow the headband to air-dry thoroughly.

5. Slide the headband around the wireframe to its original position. Reattach the

cable with the plastic retainer.

WASHING THE FOAM WINDSCREEN

The foam windscreen protects the WH30’s microphone-element from dirt
and moisture. When necessary, it can be removed and cleaned in a mild soapy
water solution. Important: Never clean the windscreen with any liquid solution

without first removing the windscreen from the microphone boom.

1. Hold the windscreen loosely by the plastic retaining ring at its base.

2. Gently pull the windscreen away from microphone. The plastic retaining ring

will expand to allow the windscreen to slip off the microphone. If necessary,

you can expand the ring manually with a small screwdriver as you pull the

windscreen.

3. Immerse the windscreen in mild soapy water and gently squeeze it several

times.

4. Rinse the windscreen in clean water and dry it with a clean cloth or paper tow-

el. Allow it to air-dry thoroughly.

5. When the windscreen is dry, slide it over the WH30 microphone until the re-

taining ring snaps into place.
